> I wonder if this is a retina display issue

I'm using an external monitor running at 5120x1440 (Samsung, not retina) only, and am experiencing the the same on Firefox.

At least not retina exclusive.

Oh wow. Sounds like I should put an upper bound on resolution. I wasn't even thinking of somebody opening the page full-screen on an ultra-wide.
